HAND-THREADING SHUTTLE.

Application filed July 8, 1915.

To all whom it may concern:

Be it known that I, IIENRY A. KENNEDY, a citizen of the United States, residing at Providence, in the county of Providence, State of Rhode Island, have invented certain new and useful Improvements in Hand- Threading Shuttles, of which the following is a specification.

My invention relates to loom-shuttles and consists of improvements in the threadingmeans therefor.

The object of my improvement is to provide a simple, strong, durable thread-guide or delivery-eye for the shuttle adapted to be set in place therein with only a slight cutting away of the wood, and arranged to be held in position without the use of pins, screws, clamps or other securing-means.

A further object of my improvement is to provide for convenient and easy threading of the yarn through the eye and also to render the guide capable of resisting wear from the constant draft of the yarn through its thread-passage.

The invention is fully described in the following specification, illustrated by the accompanying drawings, in which like reference characters designate like parts.

In the drawings :-Figure 1 is a plan view of the delivery-end of a usual form of broadloom shuttle showing my improved deliveryeye applied thereto; Fig. 2, a side view of the same; Fig. 3, a transverse, sectional View of the shuttle onthe line XX of Fig. 2; Fig. 4, a plan view of the delivery-eye by itself; and Figs. 5 and 6, two different, side views of the same.

Referring first to Figs. 4, 5 and 6, my improved guide or delivery-eye is made in the form of a cylindrical button or disk D to adapt it to be easily molded from porcelain, glass or other vitreous material capable of resisting abrasion and wear. Extending axially through the disk D, at or near its center, is a cylindrical hole h, into which leads a transverse, radial bore 6 which forms the main guide-passage for the yarn. On its top the disk D is recessed or cut away at cl to form two shoulders or abutments a, a extending outwardly from the hole It. One shoulder a extends substantially radially from the hole h in a direction at right-angles to the thread-passage 6, while Specification of Letters Patent.

the other abutment a curves tangentially from the side of the hole It outwardly to the edge of the disk D where it terminates in a rounded shoulder (1. From the edge of the shoulder a the disk is divided by a helical cut or slit 0 which terminates in the abrupt bend 0, see Fig. 5, leading into the threadpassage t. Formed on the side of the disk is a longitudinal rib or fin 7 which is adapted to fit a groove in the bore of the shuttle in which the guide is set to keep the disk from turning as more fully explained hereinafter.

Referring now to Figs. 1, 2 and 3, the disk D is fitted into the shuttle S in a very simple and efiicient manner as next described: The delivery-end of the shuttle as here shown is provided as usual with the vertical threadslit 8 extending longitudinally from the bobbin-chamber or recess R and curving around at s to open on the side of the shuttle at 8 see Fig. 2. At the bottom of the opening 8 a horizontal slit .9 leads back into a circular opening 8", the sides of which are rounded or bellied out to meetv the thread-groove g which extends along the side of the shuttle.

In applying the disk or guide D to the shuttle S it is only necessary to bore a transverse hole 8 up into the bottom of the shuttle and to score the inner side thereof with the shuttle and the disk will be held fixedly in this position by its fin 7 against turning in its bore. After the disk D is in place a wooden plug or cap P is fitted. to the bore 8 to abut its under side and its lower end is mented in place, or if desired may be secured plate to the bottom of the shuttle, although for most purposes this last holding-means is not. required.

In threading the shuttle S the yarn y is taken from the bobbin or cop B and drawn down through the slit 3 by a simple manipulation of the fingers. After it is seated at the bottom of the side-opening 8 it is drawn back through the horizontal slit s to enter it into the delivery-eye D through the automatic action of the latter. As the yarn leads across the recessed top-face (Z of the disk and is drawn back through the slit 8 it strikes against the abutment or shoulder a to direct it down into the slit c. The continued pull on the yarn will then cause it to draw down and into the bend c of the slit 0 whence it will be guided up into the thread-passage 25. It will be noted by reference to Fig. 2 that the under side of the opening 5 of the shuttle overlaps the slit 0 where the latter leads into the bend 0, so that the yarn will be prevented from whipping out from the thread-passage t after it has once been threaded in place. As the yarn delivers from the shuttle to the loom, during the weaving process, it draws outwardly "away from the thread-slit 5 across the rounded shoulder a of the abutment a on the disk D,then down throughthe threadpassage 25 and side-opening 8 see Figs. 1 and 3. The shoulder 61. projectsslightly be yond the side of the slit 8 so that the yarn will be kept'from contact therewith to prevent it from wearing away the wood of the shuttle.

It will be seen that my improved deliveryeye or thread-guide is extremely simple in design and small in dimensions, besides being of a form which readily adapts it to be molded from porcelain or similar material. It can be applied to the shuttle by cutting away a very slight portion of the woo: thereof, and hence the shuttle is not mutilated or weakened as is usually the case. The guide-eye being relatively small and fitting so closely in its bore is less liable to be cracked or broken and hence possesses greater durability. Furthermore, it can be set in place in "the shuttle with practically only one operation thereon, that of boring the hole 8 so that the cost of applying it is very little. All fastening-screws, pins or other securing-devices are dispensed with, while at the same time the eye is so firmly embedded in and protected by the wood of the shuttle that it is practically proof against damage or breakage. In operation the shuttle is most easily and conveniently threaded through the automatic action of the eye, and finally my improvement gives a particularly'neat and finished appearance to the whole shuttle.

Various modifications might be made in the form and construction of the parts of my improved device without departing from the spirit or scope of the invention;

Therefore, without limiting myself to the cxact embodiment shown and described, what I claim is 1. A delivery-eye for loom-shuttles constructed in the form of a disk-like plug having an axial hole extending through it from-end to end with a radial thread-passage leading from the axial hole to the periphery of the plug, the upper end of the plug being formed with shoulder-like abutments extending across its top, and a relatively narrow helical slit cut through the plug from the side of its axial hole to its outer surface and inclineddownwardly from the edge of one of the abutments to lead into the radial thread-passage.

A delivery-eye for loom-shuttles molded from vitreous material, such as porcelain or glass, in the form of a disk-like button having an axial hole extending through it from end to end with a radial thread-passage leading from the axial hole to the side of the disk, the top of the disk being recessed toform shoulder-like ahutments extending from the axial hole to the edges of the disk, and a helical slit cut down through the disk from the recessed'portion of its top and extending with a sharp bend up into the thread-passage to provide an entrance for the yarn thereto.

3. In a hand-threading shuttle provided with the longitudinal bobbin-chamber having a vertical thread-slit leading therefrom to the side of the shuttle and a horizontal slit extending from the end of the vertical slit back into a transverse side-opening, the combination of a cylindrical disk-like plug fitted to a vertical bore at the end of the shuttle and formed with an axially-extend ing hole having a radial thread-passage leading therefrom to the 'side of the plug to register with the side-opening in the'shuttle, the top of the plug being recessed to form upstanding shoulder-like abutments, a'nd'one side of the plug out through with a slit extending from its shouldered portion down into the thread-passage to adapt the yarn to be threaded throughthe slit in the shuttle and thence through the slit in the plug to seat it in the thread-passage thereof.

In testimony whereof Iaiiix my signature in presence of two witnesses.
